Romain Naour b29fe22257 configs/beagleboneai64_defconfig: new defconfig
Adds support for BeagleBone AI-64 board by introducing the
beagleboneai64_defconfig file and related support files.

The BeagleBone AI-64 uses the TI J721E SoC, also known as DRA829, also
known as TDA4VM.

Retrieve BSP settings from meta-ti (may be useful for other TI boards):

- This defconfig requires u-boot binman support added in u-boot since
  2023.10.
  See FOSDEM 2024 talk by TI folks about Binman and how it simplify
  the overall boot-loader build flow [1].

- Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_TARGET_BOARD = "generic"
  meta-ti]$ git grep TFA_BOARD
  meta-ti-bsp/conf/machine/beagleplay.conf:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/am62axx.inc:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/am62pxx.inc:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/am62xx.inc:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/am64xx.inc:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/am65xx.inc:TFA_BOARD = "generic"
  meta-ti-bsp/conf/machine/include/j7200.inc:TFA_BOARD = "generic"
  meta-ti-bsp/conf/machine/include/j721e.inc:TFA_BOARD = "generic"
  meta-ti-bsp/conf/machine/include/j721s2.inc:TFA_BOARD = "generic"
  meta-ti-bsp/conf/machine/include/j722s.inc:TFA_BOARD = "lite"
  meta-ti-bsp/conf/machine/include/j784s4.inc:TFA_BOARD = "j784s4"

- Set BR2_TARGET_UBOOT_NEEDS_ATF_BL31 to provide BL31 variable pointing
  to ATF bl31.bin to the U-Boot build process [2].

- Set BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE to OP-TEE as BL32
  secure payload. meta-ti set "SPD=opteed" to build ATF [3].

- Set BR2_TARGET_OPTEE_OS_PLATFORM to "k3-j721e".
  meta-ti uses the OPTEEMACHINE to set optee-os platform [4].
  meta-ti]$ git grep OPTEEMACHINE
  meta-ti-bsp/conf/machine/am437x-hs-evm.conf:OPTEEMACHINE = "ti-am43xx"
  meta-ti-bsp/conf/machine/am57xx-hs-evm.conf:OPTEEMACHINE = "ti-am57xx"
  meta-ti-bsp/conf/machine/beagleplay.conf:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/dra7xx-hs-evm.conf:OPTEEMACHINE = "ti-dra7xx"
  meta-ti-bsp/conf/machine/include/am62axx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am62pxx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am62xx.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/am64xx.inc:OPTEEMACHINE = "k3-am64x"
  meta-ti-bsp/conf/machine/include/am65xx.inc:OPTEEMACHINE = "k3-am65x"
  meta-ti-bsp/conf/machine/include/j7200.inc:OPTEEMACHINE = "k3-j721e"
  meta-ti-bsp/conf/machine/include/j721e.inc:OPTEEMACHINE = "k3-j721e"
  meta-ti-bsp/conf/machine/include/j721s2.inc:OPTEEMACHINE = "k3-j784s4"
  meta-ti-bsp/conf/machine/include/j722s.inc:OPTEEMACHINE = "k3-am62x"
  meta-ti-bsp/conf/machine/include/j784s4.inc:OPTEEMACHINE = "k3-j784s4"

- Use j721e_beagleboneai64_a72 and j721e_beagleboneai64_r5 u-boot
  defconfigs introduced in u-boot v2024.04.

- u-boot distroboot (bootflow) detect extlinux.conf file from the first
  SDcard partition, se we have to install the kernel and its dtb file.
  Use devicetreedir instead of devicetree in extlinux.conf file to
  avoid hardcoding the devicetree file name. TI boards are able to
  retrieve dtb file name from an EEPROM (see TI_I2C_BOARD_DETECT in
  uboot).

- Provide a hash file for all custom package version
  (arm-trusted-firmware, linux, ti-k3-r5-loader, uboot) to enable
  BR2_DOWNLOAD_FORCE_CHECK_HASHES.
